James K. Polk

Presidency

What measure led to Polk’s success in lowering the tariff?

The Walker Tariff Act of 1846, named after Polk’s secretary of the treasury, Robert J. Walker, achieved the president’s objective in lowering the tariffs that had been passed by the Whigs in 1842. Polk faced significant opposition in Congress. Vice President George M. Dallas cast the tie-breaking vote in the Senate that led to the law’s successful passage.
